1. Hearing Rehabilitation through Bone-Conducted Sound Stimulation: Preliminary Results
Abstract Introduction The bone-anchored hearing aid (BAHA) is a bone conduction system that transmits the sound directly to the inner ear by surpassing the skin impedance and the subcutaneous tissue. It is indicated for patients with mixed, conductive and unilateral sensorineural hearing loss who did not benefit from conventional hearing aids (HAs). Althou

2. Crianças prematuras: estudo da supressão das emissões otoacústicas e da resolução temporal. / Premature children: study of suppression effect of otoacoustic emissions and temporal resolution
Objective: Determine the occurrence of the suppression of otoacoustic emissions, the temporal resolution hearing skill and the association between the results of these assessments and premature birth as well as the presence of signs suggestive of an alteration in auditory processing during development, in premature, below 2000g at birth. Methods: Forty low-i

3. Text not informed by the author / Efeito de áudio em 3D na compreensibilidade de uma entre duas mensagens simultâneas em língua estrangeira: aplicação em grupos de controladores de tráfego aéreo experientes e novatos
This study aimed to verify whether the dichotic or spatialized (3D audio system) presentation of two simultaneous sentences in English facilitate the identification of a target information comparing to dihotic (nonspatialized) presentation. The subjects in this study were air traffic controllers having as L1 (mother tongue) Brazilian Portuguese, and were div

4. Mobilidade do idoso : proposta para uma avaliação inicial
An instrument for the inicial assessment of the mobility in the elderly was proposed and put into practice in the evaluation of 30 people 70 years old and over, in an institution. The results were compared to those obtained with the application of the Barthel index, a scale to assess the basic activities of daily living (AOL), and to the level of independenc

5. Biosocial variables and auditory acuity as risk factors for non-fatal childhood injuries in Greece.
OBJECTIVES: To examine whether biosocial variables and auditory acuity are risk factors for injuries among children. SETTING: Children with injuries who presented at the emergency clinics of one of the two university hospitals for children in Athens, Greece between December 1993 and April 1994. METHODS: 144 children aged 5-14 years, residents of Athens, were

6. Effect of furosemide on aminoglycoside-induced nephrotoxicity and auditory toxicity in humans.
We analyzed data from three prospective, controlled, randomized, double-blind clinical trails to determine whether furosemide increases the nephrotoxicity and auditory toxicity of aminoglycosides. All patients who received at least 72 h of treatment and who had no other cause for nephrotoxicity or auditory toxicity were included in the analysis. Nephrotoxici

7. Plasticity in the neural coding of auditory space in the mammalian brain
Sound localization relies on the neural processing of monaural and binaural spatial cues that arise from the way sounds interact with the head and external ears. Neurophysiological studies of animals raised with abnormal sensory inputs show that the map of auditory space in the superior colliculus is shaped during development by both auditory and visual

8. A new treatment for congenital nystagmus.
Congenital nystagmus is a disorder of eye movement with an associated reduction in visual acuity. The latter is mainly due to the intensity of the nystagmus (amplitude times frequency) allowing the object of regard to spend only a short time on the fovea. Training patients by an auditory feedback technique to control the nystagmus enables visual sensitivity

9. Location Coding by Opponent Neural Populations in the Auditory Cortex
Although the auditory cortex plays a necessary role in sound localization, physiological investigations in the cortex reveal inhomogeneous sampling of auditory space that is difficult to reconcile with localization behavior under the assumption of local spatial coding. Most neurons respond maximally to sounds located far to the left or right side, with few n

10. Effect of viewing high luminance gratings on the amblyopic visual system.
Five amblyopes viewed high contrast square wave gratings of 8 different spatial frequencies all presented at very high luminance. They were required to indicate the orientation of the grating, horizontal or vertical, and received immediate auditory feedback if incorrect. Each amblyope viewed 480 grating presentations daily for 15 days over 3 weeks. After thi

11. Control of a Depolarizing GABAergic Input in an Auditory Coincidence Detection Circuit
Neurons in the chicken nucleus laminaris (NL), the third-order auditory neurons that detect the interaural time differences that enable animals to localize sounds in the horizontal plane, receive glutamatergic excitation from the cochlear nucleus magnocellularis (NM) and GABAergic inhibition from the ipsilateral superior olivary nucleus. Here, we study metab

12. Delay accuracy in bat sonar is related to the reciprocal of normalized echo bandwidth, or Q
Big brown bats (Eptesicus fuscus) emit wideband, frequency-modulated biosonar sounds and perceive the distance to objects from the delay of echoes. Bats remember delays and patterns of delay from one broadcast to the next, and they may rely on delays to perceive target scenes. While emitting a series of broadcasts, they can detect very small changes in delay
